How To Make Your Child a Tax-Free Multimillionaire by Retirement
It’s a clever strategy: contribute to your child’s Roth IRA and let the money compound on its own for five or six decades. They could retire with $5-10 million without ever paying a dime in taxes. Zero taxes. Ever. It's the kind of financial move that sounds too good to be true.
It's not, but there are rules. Lots of them. Navigate them correctly, and you unlock generational wealth. Get them wrong, and you're inviting an IRS audit. Here's exactly how to do this the right way.

Your Child Needs Real, Earned Income
Here's the non-negotiable requirement: your child must have actual W2 or 1099 income to contribute to a Roth IRA. You can't rebrand their allowance or chores as "wages" and hope the IRS doesn't notice.
Americans can contribute up to the lesser of their earned income or $7,500 annually to an IRA. That's the ceiling. If your child earned $3,000, they can contribute $3,000. If they earned nothing, they contribute nothing.
“If you own a business, employing your children is completely legal if the work is real and age-appropriate for them,” noted Oxana Hendrix, a certified public accountant (CPA) with JustAnswer. “Kids can work as mail couriers, office admins or marketers and social media leads.
"If you don’t have a business, kids can earn income as dog walkers, babysitters, lawn mowers, garbage can cleaners or any other entrepreneurial venture.”
The IRS won't bat an eye at legitimate work. But they will if something smells off.
Know the IRS Red Flags
Don't trigger an audit by avoiding these common mistakes:
Unrealistically high compensation for the work
Round-dollar payments without supporting documentation
Age-inappropriate duties
Missing timesheets
No proof that work actually happened
Mischaracterizing household allowance as "wages"
Logan Allec, a CPA with Choice Tax Relief offers a clear example: “Maybe you have a bakery, and you tell your kids, ‘Hey, today we're going to take pictures for Mommy's business, and I want you to bite into these cookies and make a face that shows they're yummy while I take pictures!’ and you compensate them for that.
“The IRS takes umbrage when parents pay their kid thousands of dollars for a simple photo shoot and call it earned income. Ask yourself, ‘What's the going rate in my area to pay some unrelated kid I don't know to do this task?’ Document that data and put it in your files in case the IRS ever comes knocking.”
Document Everything
If you own a business, put your child on payroll as a W2 employee. This creates a paper trail directly to the IRS and normalizes their income in the system.
“A dependent child is only required to file a federal tax return if their earned income exceeds the standard deduction: $16,100 for 2026,” said Hendrix. That’s more than double the IRA contribution limit of $7,500.
“However, if they aren’t on payroll, then filing an informational Form 1040 is recommended as it creates an official IRS paper trail verifying the exact earned income reported, shielding the Roth IRA from future audit challenges.”
The story changes if your child earns 1099 income or other self-employment income. “If they earn $400 or more in net self-employment income, then they are required to file a return to pay self-employment tax.”
Regardless of the income type, treat your child like an actual employee: create a job description, document their tasks and duties, keep timesheets, retain proof of payment and open a checking account for direct deposits. Your state may also have different filing thresholds than the federal government, so verify those requirements too.
You Can Contribute the Money Yourself
While your child needs to earn income in order to contribute to a Roth IRA, they don’t need to be the ones who contribute it.
If you prefer, you can let them keep their earnings, and you can contribute your own money to their IRA. For that matter, grandparents or aunts and uncles can contribute instead. If you want your kid to participate in saving for their future, you can negotiate a split — maybe they contribute half and you cover the other half.
The only rule: the contribution amount can't exceed their earned income for the year.
Setting Up the Account
Open a custodial Roth IRA for free through your regular investment brokerage — Schwab, Vanguard, Fidelity or whoever you use. Your child will automatically take possession of the account when they reach the age of majority (usually 18 or 21, depending on your state).
Your child isn't limited to a standard Roth IRA either. Christopher Carusa, author of "From Cradle to Retirement," noted that "you could set up your child with a 401(k) or an SEP-IRA, which allow children to save more than the IRA maximum of $7,500."
As your child gets older, use the account as a teaching tool for investing, compound returns, tax optimization and financial literacy. And remember, Roth IRAs are flexible. Your child can withdraw money penalty-free for college tuition or up to $10,000 for a first-home down payment. The money isn't locked away forever if life circumstances change.
The Bottom Line
A Roth IRA with decades to compound is one of the most powerful wealth-building tools available to families. Starting at age 10 or 12 with even modest contributions can genuinely set your child up to retire with millions and owe zero in federal taxes.
Just make sure you color within the lines of the IRS rules. The strategy only works if it survives an audit. Document aggressively, pay market-rate wages and treat your child's work as legitimate. Do that, and you've got a generational wealth multiplier that actually works.
